Description

【考案の詳細な説明】〔産業上の利用分野〕地下に埋設するアース棒に針を突出させておく
と、接地抵抗を低下させる上で効果の大きいこと
が知られているが、針付金属棒の製作は決して容
易でない。本考案は製作を比較的容易にした針付
アース棒に関するものである。[Detailed explanation of the invention] [Industrial field of application] It is known that having a needle protruding from a grounding rod buried underground is highly effective in reducing grounding resistance. Making sticks is never easy. The present invention relates to a ground rod with a needle that is relatively easy to manufacture.

[Conventional technology]

外周に半径方向の針を突出させたリングをつぎ
つぎと金属棒へ被挿し、溶着した構造が知られて
いる。針付リングの製作にも複数のリングの溶着
にも多くの工数を要することが問題であつた。 A structure is known in which rings with radial needles protruding from the outer periphery are successively inserted into metal rods and welded. The problem is that it takes a lot of man-hours to manufacture the needle ring and to weld a plurality of rings together.

〔問題点を解決するための手段〕本考案は針を螺旋状に設けることによつてこの
問題の改良に寄与したものである。[Means for solving the problem] The present invention contributes to the improvement of this problem by providing the needle in a spiral shape.

〔Example〕

本考案は第１図に示す如く、金属の棒１或は管
へＵ形断面の支持金具２を螺旋状に巻きつけ、こ
の支持金具から複数の針３を突出させたものであ
る。 In the present invention, as shown in FIG. 1, a support fitting 2 having a U-shaped cross section is spirally wound around a metal rod 1 or a tube, and a plurality of needles 3 are made to protrude from the support fitting.

これの製作にはまず第２図の如く複数本の針３
の目孔へ細軸４を被挿して、針の間隔、姿勢を整
えたものを作る。別にテープ状板を軸線方向に沿
いＵ形に折曲げた支持金具２を用意し、上記針群
の基部をはさんでリベツト５で固着し、櫛状体６
とする。これを金属棒１へ直立させて螺旋状に巻
きつけ溶着する。 To make this, first, as shown in Figure 2, use multiple needles 3.
Insert the fine shaft 4 into the eye hole to adjust the needle spacing and posture. Separately, a supporting metal fitting 2 is prepared by bending a tape-like plate into a U shape along the axial direction, and the base of the needle group is sandwiched and fixed with a rivet 5.
shall be. This is placed upright on the metal rod 1, wound spirally, and welded.

第４図は他の実施例で、針に代えて針金束７を
用いる。針金束は二つ折にし、折曲基部へ細軸４
を挿通してブラシ状体８とする。その他は針付の
場合と同じである。 FIG. 4 shows another embodiment in which a wire bundle 7 is used instead of the needle. Fold the wire bundle in half and attach the thin shaft 4 to the base of the bend.
is inserted to form the brush-like body 8. Other details are the same as those with needles.

〔effect〕

公知のものに較べ著しく製作工数を減少する。 The number of manufacturing steps is significantly reduced compared to known products.
